ALONZO amnion, or B5521 WISCONSIN. MACHINE FOR TRiMMiNC-i AND SLlTTlNG PAPER.

To all whom it may concern.- Be it known that I, Amman A'Lnnron a citizen of the United States, residing at eloit, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Machines for Slitting and Trimming Paper, of which the following is a specification.

The resent invention relates to that class of mac esthat are used for trimmin paper to different widths, andmore particu arly to that subclass of machines that are provided with two sets of slitters or trimmers so arranged that when one set is working the other .set is idle and accessible for the purpose of laterally adjusting its paired slitters relativel to each other, so as to be in readinose to e moved into working position as soon as needed for trimming a different width, the set previously working being by the same operation moved out of working position. Machines of this type are well known in the art. As heretofore constructed the paired slitters of each set move together and m the same direction in bein moved into and out of working position, an since the cooperatin slitters of each air must when working e upon opposite sides of the paper it follows that one slitter of each pair is moved across the plane which the palplelr occupies while being slit or trimmed. 's necessitates breaking the paper each time the one set is to be moved into and the other out of working position. i

The principal object of the present invention is to provide a machine of such construc tion that the paper need not be brokenin order to make this change from one width to another, and other ob1ects are to otherwise improve the construction of machines of this class. In order to accomplish these objects, I use two sets of slitters, each of which sets comprises two (or moreipairs of cor"; crating slitters so arranged that when wor ng the cooperating slitters of each pair are upon opposits sides of the aper, as is customary, and provide means or me the cooperatin slitters of each set tower and from see other and toward and from the plane of the paper, so that none of the slitters crosses said plane in mo into or out of working osition. In addition to this the slitters o the two sets are so connected that as one set is moving into working osition the other set 18 moving out of wor g position, so that Specification of Letters Intent. Application flied August 10, 1904. Serial Hp. 220,234;

there is no loss of either time or paper in changing the machine. I believe myself to be the first to provide a slitting and trimming machine of such con struction that it is not necessa to break the paper in changing from onewi th to another, or, in other words, a machine in which the cooperating slitters are moved toward and from each other without moving either across the plane of the paper, and I therefore desire it to e understood that the invention is not limited to mechanism of any particular construction for so moving them. Their movement in opposite directions being suggested, many difierent mechanisms for movi them and also for making theaction of t e two sets reciprocal will readily sug est themselves, and while I have illustra the invention under three different modifications there are others that are within its scope.

In the accom anying drawings, which are made a part of t specification, F e 1 is a side elevation of a machine embo the invention in its referred form. Fig. 2 is a plan view thereo Fig. '3 is a vertical transverse section thereof on the line 3 3, Fig. 1. Fig. 4 is a detail of the ca Fig. 5 is a detail of the meansfor ateral separating the paired slitters.- Figs. 6 an 7 are elevations of modifications.

The frame 1 may be of any desired construction so long as it meets the requirements of the machine. It has brackets 2 and 3 so porting two rolls of paper 4 and 5, stands. s 6, supporting a foot-board 7 adjustable standards 8, sup orting one of the guardboards 9, means or so porting the drivingshaft 11, and stander. s 12, supporting the other guard board i3 and other parts or inafter described.

As before stated, there are two sets of slitters, and each of these sets (as shown inthe drawings) consists of two pairs of slitters, and the two 'slitters 14 and 15 of each pair are arran ed in operative relation to each other. T e lower slitters 14 of each set are carried by a shaft 16, upon which they are laterally ad'ujstable relatively to each other (the term latereliy""heing herein used with to the machine) in customary manthe shafts 16 of the two sets are boxes 17, carried at the opposite arms 18, which are on stub-shafts 19, supported by the stan ards 12. The no shafts 16 rojcct beyond the boxes 17 at one end, and t ieir projecting portions carry gearwheels 20 that are adapted to mesh alternately with apinion 21 carried by the drivingshaft 11, the parts being so proportioned and arranged that when the rock-arms are tilted in one direction one of the gear-wheels 20 will be in mesh with the inion 21 and the other out of mesh, and w en the rock-arms are tilted in the opposite direction these conditions will be reversed. The gear-wheels 20 are also adapted to mesh with corresponding gear-wheels 22 on the projecting ends of shafts 23, which carry the upper slitters 15 of the two sets. These shafts are mounted to both revolve and move endwise in bearings carried at the extremities of arms24, that are mounted to rock or oscillate on stub-shafts 25, supported by'the standards 12. The up er slitters of both sets are laterally adjusta le upon their shafts, but are incapableof turning thereon. They are held in contact with the faces of the slitters 14 by coiled springs 26, each of which bears in one direction against one of the slitters and in the other direction against one of a corresponding number of collars 27, that are adjustabl secured to the shafts, the movement of the s 'tters under the influence of the springs being limited by collars 28, adj ustably secured to the shafts.

In addition to being laterally adjustable relatively to each other the u per slitters of each set are laterally movab e to ether b reason of the endwise movability o the sha carryi them. One end of the shaft has a reduce portion 29, which is surrounded by a sleeve 30, one end of which abuts against the shoulder resulting from the reduction of the shaft and the other end of which abuts ainst a collar 31, secured to the reduced portion of the shaft, sothat the shaft is free to turn in the sleeve, but is inca able of endwise movement therein. The s eeve is rovided with a rigid radial arm or handle 32, y which it may be artially rotated, and it is provided also wit a spirally-disposed slot 33, into which projects a stu or pin 34, carried at the box 35 of the arm 24. This sleeve in fact forms the bearing in which the shaft revolves, and when the sleeve is turned in its bearing the slot 33 will act as a cam and cooperating with the fixed pin or stud 34 will move the shaft 23 endwise, mixing the slitters with it for a p ose herein r described. 7

or the purpose of rockin the arms 18 and 24 in opposite directions, an thereby movin the cooperati slitters of one set towar each other and mto working positions and at the same time moving the cooperating slitters of the other set a art and into osition to permit of their be adjusted, inks 36 have their upper ends jointed to the arms, respectively, and their lower ends jointed to a partial disk or sector or equivalent device 37, secured to the shaft 38 of a hand-wheel 39. In mechanical effect the device 37 is the equivalent of two radial arms, and the links are connected toit at such oints that as it is carried around b the she the links are moved endwise in di erent directions.

In Figs. 1 to 4 the'cooperating slitters of"- tance a art. This is done by adjusting the lower sitters exactly to thetpositions they are to occupy when at work and adjusting the upper slitters to a correspondin distance a art, but at such positions on t eir shaft t at when the shaft is in normal position- (with respect to its endwise movement) they will lie in the vertical planes of the lower slitters, as shown in Figs. 2 and 3. If the handle 32 is then thrown to the position indicated by dotted lines in Fig. l, the shaft will be moved endwise (toward the left --hand side of Fig. 3) and the slitters 15 of the second set Wlll be moved to the positions indicated by dotted lines in Fig. 2. This is to permit their ri heries to pass the lower slitters when th s fiend-wheel 39 is turned in the proper directionto move them toward each other, and after this is done the shaft is moved endwise in the reverse direction by the handle 32 to the position shown restori by fuIl Fnes, and this movement brings the fiat faces of the upper slitters to bear against the flat faces of the lower slitters and puts the s rings 26 under the proper tension. To this latter end the parts are so ad'usted that the slitters come together before t e endwise movement of the shaft is completed, thus leaving a slight clearance between the hubs of the slitters l5 and the collars 28 as shown in Figs. 2 and 3 with respect to the first set. When the work to be done by the first set is completed and the second set has been adjusted as just described, the lever 32 of the first set is moved, so as to move the shaft endwise and separate the flat faces of the coo ilerating slitters of the first set. The handw eel 39 is then turned in the proper direction and the arms 18 and 24 thereby rocked,

so as to move the slitters of the first set apart' and move the slitters of the second set toward each other, so that their peripheries slightly pass the plane of the pa er. The lever 32 of the second set is than t own in the proper direction to move the shaft endwise and bring the fiat faces of the cooperating slitters into contact, as alread described, and the machine is ready for t e next run and the slitters of the first set in position to be adjusted.

In Fig. 6 the rock-arms 18 and 24 are secured to shafts 40 and 41, that turn bearenasso ings in the standards 12 and are located at such distance apart that when either set is in working osition the rock-arms are vertical and the sliafts carry ear-wheels 42, meshin with a pinion 43 on t e shaft of a hand-whee 44. Otherwise the parts may be substantially as alreadg described. Furthermore, any other suite is means may be used for moving the arms 18 and 24,

In Fig. 7 the shafts 16 and 23 are lournaled in bearings carried by slides 45, that are mounted on vertical guides 46 on the standards 12, so that they are capable of vertica movement thereon. Any suitable means may be used for moving the slides, so that the slitters of one set are moved toward each other while the slitters of the other set are moved apart. In the drawings I have shown the slides as being jointed to the up or ends of links 47, (one for each slide,) t e lower ends of which are jointed to a part 48, similar to the part 37, already described, so that when the shaft carrying said part is turned one set of links will be moved upward, thereby moving upward the upper slitters of the" first set and the lower slittcrs of the second set, and the other set of links will at the same time be moved downward, thereby moving downward the lower slitters of the first set and the u per slitters ol the second set. For holding tile slitters in operative relation to each other any desired mechanism may be used. In the drawings I have shown a notched wheel 48, secured to the shaft 38, a bolt 49, adapted to enter one or the other of said notches, a spring 50 for holding the bolt normally in engagement, and a treadle or foot- )iece 51 for retracting it.

What I claim as new, and desire to secure by Letters Patent, is-
